What is the reaction of b-naphthol with sodium hydroxide?
It creates a brownish liquid that makes an azo dye called Para Red when it is combined with a bright yellow mixture created from para-nitroaniline/HCl/sodium nitrite. So the reaction that you are talking about basically makes a brownish dye.
What azo dye is formed when salicylic acid reacts with amino benzoinc acid?
3,4'-dicarboxy-4-hydroxy azo benzene.it is a coupling reaction...........it forms a azo dye.when salicylic acid reacts with amino benzoinc acid.. initially amino benzoinc acidreacts with nitrous acid and hydrochloric acid to form azo group....azo group: -N=N-then that azo compound react with salicylic acid to form an azo dye(3,4'-dicarboxy-4-hydroxy azo benzene).C6H4COOH(OH)-salicylic acidCH2NC6H4CO2H- amino benzoinc acid.H2NC6H4CO2H+HNO2+HCL-->CL-N=N-C6H4COOH(AZO COMPOUND)3,4'-dicarboxy-4-hydroxy azo benzene.(AZO DYE)
Is azo dye and diazo compound same thingh?
No, azo dyes are a type of synthetic dye characterized by the azo group (-N=N-) in their molecular structure, while diazo compounds are a class of organic compounds that contain the diazo group (-N=N-). Azo dyes are a specific application of diazo compounds in dye chemistry, but not all diazo compounds are azo dyes.
How many absorption bands are in uv spectrum for azo polyamides?
Azo polyamides typically exhibit absorption bands in the UV spectrum due to the presence of azo groups. The exact number of absorption bands can vary depending on the specific chemical structure of the polymer and the environment. Typically, azo polyamides show absorption bands in the range of 300-400 nm.
Why azo dyes are resticted for textile dyeing printing?
The azo dyes that are restricted for textile use have been so restricted because they cause skin hypersensitivity and allergies. Not all azo dyes are so restricted--there are eleven azo dyes that are approved for use in food.
Is phenyl azo beta naphthol saturated or not?
Phenyl azo beta naphthol is not a saturated compound. It contains multiple double bonds in its molecular structure, which makes it unsaturated.
What is the melting point of phenyl-azo beta-naphthol?
The melting point of phenylazo- beta-naphthol is somewhere from 131 to 133 degrees Celsius. Phenylazo- beta-naphthol is also called as Sudan I.
What happens when benzene diazonium chloride is treated with alkaline 2-naphthol?
When benzene diazonium chloride is treated with alkaline 2-naphthol, a diazo-coupling reaction occurs. This results in the formation of an azo dye, specifically the orange-red compound called Sudan I. This reaction is commonly used for the synthesis of azo dyes in organic chemistry.
In diazotization beta naphthol used?
Actually beta naphthol is not used in diazotization.It is used to confirm the formation of diazonium salt.Because the diazonium salt so formed undergo the COUPLING REACTION with beta naphthol to form a ORANGE DYE or DYESTUFF. eg. aniline with HCl and Sodium Nitrite followed by the treatment with beta naphthol in NaOH at 0-5 degree celcius forms Phenyl azo-beta naphthol(orange).
What is the reaction of b-naphthol with sodium hydroxide?
It creates a brownish liquid that makes an azo dye called Para Red when it is combined with a bright yellow mixture created from para-nitroaniline/HCl/sodium nitrite. So the reaction that you are talking about basically makes a brownish dye.
What is the birth name of Anatoliy Azo?
Anatoliy Azo's birth name is Azo, Anatoli Georgiyevich.
Can you take Aleve and azo together?

What is an azo dye?
An azo dye is any of a number of yellow to red synthetic dyes which contain an azo or diimide functional group.

When was Assaf Azo born?
Assaf Azo was born on 1984-05-17.
What is azo gantrisin?
Azo Gantrisin is used for urinary tract infections. The medicine can also be used bacterial infections and is also known as Azo Gantanol,
